It is often necessary to prepare a dilute solution from a more concentrated solution rather than starting from a solid and just dissolving it then adding water. This technique is called serial dilution. Give all the steps necessary to obtain 100 mL of a 1.7 x 10-5 M solution using a solution prepared by dissolving 0.3 grams of a Red dye (molar mass of 869 g/mol) dissolved in water in a 100 mL capacity volumetric flask. Assume you have access to deionized water, 1.0mL pipette, 5.0 mL pipette, 10.0 mL pipette, and 100.0 mL volumetric flasks.
